PSP: Internal USB Charger by Acid Mods

[Anger]

like everyone i also am wondering how this could be done. does usb provide enough power to actually charge the psp?
i would really like this to be possible but i think it would cause problems with other devices that expect no power to be drawn from them, like the camera addon or the gps addon. can someone do this mod and find out if it affects those devices?

[Cloudhunter]

It won't effect the devices, as the camera and GPS in fact takes power from two points on the left and the right side of the PSP.

i dont see why sony couldnt do that in the first place. it would have been better to be able to charge using the normal charger place, and to be able to charge using the usb port.

there must be a reason that they chose not to do it like that in the first place.

I want a ton of crazy mods, but it would take a good amount of time

Flashin ur battery everytime u connect ur USB is really bad idea. It might shorten the life of the battery. Unless they make a switch for it.

Wow SONY should have definently done this in the beggining, there would have even been a sufficient amount of room for the second analog numb if they removed the DC outlet charging port.

I'm worried about what might happen if you have it plugged into the wall and then decide to connect the USB. Might it not send unwanted voltage through your USB cable into your computer?

This mod seems to have potential, but may need some safeguards. Maybe some transistors to only allow the electricity to flow in one direction.

I'm also worried about the camera and gps. While they may seem to work, their voltage could be lowered as they try to charge the same battery that they get their power from and they may not work well if at all. Yes, I know they use the pogo pins on the side to draw power, but that still comes from the battery.

Perhaps a circuit that would break if the additional USB power supply was accessed would prevent these problems as well.

It's all possible and could remain quite small if done right. But cost/benefit analysis may conclude that it's better off not being done.

EDIT:
I just checked the original post on the acidmods forums and there seem to be no answers to any of these questions yet except that you can still transfer files (which was pretty obvious considering that USB chargers have existed for a while).
